I am embedding mozilla in my application. Initially I tried with
XULRunner release build from one of the nightlies and it failed at
nsIWebNavigation->LoadURI().
To debug into mozilla code I did a debug build of XULRunner on my
machine and used it for embedding. With this debug version XPCOM is
not being initialized properly. It is failing trying to register the
DBus module. Here is the stack trace leading to a segfault:

Just before the seg fault I get this assert message:
###!!! ASSERTION: Uh, JS context w/o a thread?: 'cx->thread', file /
home/Shivaprasad/xulrunner/mozilla/js/src/xpconnect/src/xpcprivate.h,
line 3089
Please let me know what I am missing.

Brahmana.
